You can customize your charts and channels in several ways for your needs.

Axis

By default 5 axis on each side of the chart are available. If you need mode, just take a look into frontend/View/Index/dialog.chart.tpl :-)

The axis unit label is detected from the 1^st channel assign to this axis, so take care to attach channels of the same unit to the same axis.

Series display type

• Line
• Spline
• Spline with min./max. range
• Spline with area
• Bar
• Scatter

Dash style

Use these styles for visual alignment of channels.

Line width

Use these different 3 line width for highlighting channels.

Mark reading values

You can mark several values with a value label. "All" is only useful for bar charts

Period values

Shows for meter channels the data per selected aggregation period and not the total over time.

Show for example production/consumption per day as bar chart.

Presentation

For meter channels you can show the values according to the consolidation period, see the Bar chart example for details.

Color

Some collors are pre-defined, you can choose from the whole color range.

Shadow

Draw a white shadow behind the line to make the line better visible.

Color for values below/above threshold

To make e.g. negative values more visible, you can show them in a different color. (example)

Time range

Sometimes, when you show channels only filled during daylight times and 24hr channels together, you are interested only in a part of the whole data. In this case you can specify for the 24hr channel a time range to display, see the limited time range example.

Legend

You can hide channels from legend, e.g. for the sunrise/sunset marker channel. (example)

Chart position

The channels are displayed in the chart by default in the same order as in the channels overview list. Here you can move them more to back/front.
